This is the aluminum version (just like the vintage Les Pauls) of the stop tailpiece that secures solidly to your guitar and won't come loose or fall off when the strings are off. This TonePros System II tailpiece is the same that you will find installed on vintage and historic reissue guitars and will look identical to your stock piece because it's made from the actual OEM tailpiece used on your guitar, but the new version locks in solid, creating far more sustain. You won't believe the difference, and you will never go back!
